Hi,

Check in the Company Profile on the System Options tab. Do you have 'Calculate backorder' turned on? If so, Adagio OE will calculate the number of items backordered on the order. If someone zeroes out the backordered amount and nothing has been shipped, the item is completed when the order is posted.

If 'Calculate backorder' is turned off in the Profile, then it is acceptable to have a quantity on order but nothing shipped or on backorder. The item isn't automatically completed when posted.
